1962, Leshan county government found a closed cave in front of the Buddha's abdomen when it was carrying out large-scale maintenance of Leshan giant Buddha. Its discovery seems to confirm the eternal legend that there is a famous "treasure cave" on the giant Buddha. The Treasure Cave is located in the middle of the Buddha's chest, with a height of 3.3m, a width of 1 m and a depth of 2m. Traditionally, the caves of Buddha statues are usually dug in the back of the Buddha, while the treasure caves are dug in the chest. Why is this? There is no accurate answer so far. But what is certain is that this cave has been opened many times in history and many valuables have been stolen.
Lingshan Cave, one of the top ten famous cave attractions, is located in Wuwang, Jiyuan, Henan Province, on the mountainside of Lingshan peak in the east of Wangmudong, and is also called Wuwangdong with Wangmudong. The holes in the cave crisscross and circle like a maze, which is called "Forty-eight Street". It is said that its bottomless pit is connected with the Empress Dowager Cave from top to bottom. There are five caves in Lingshan Cave, four of which are suspended on cliffs. The entrance of the cave is a masonry structure with a sloping gate built in the 25th year of Jiajing in Ming Dynasty (1546), and its decoration and structure are all carved from bluestone. Into the mountain gate, that is, the main entrance, the front of the gate is engraved with the words "the first hole".
